When one speaks from a position of apparently having little knowledge of the subject at hand, they may try to insinuate something about me. But then you may have to be prepared to get your foot out of your mouth in public. I do not post things about which I am not pretty well educated and well informed. I will await your response
T
the loach
. But first read everything below and educate yourself and then fee free to post your own scientific references which refute anything below. I do not care if you apologize for your insinuation or not. But hopefully, you will come away having learned a lot.
I do not expect most hobbyists to get through everything below. You have to be a bit of a "nut" to make the commitment to spend the time required. I am that "nutty." But I feel compelled to defend myself. So, I will explain it again. When a tank is cycled, there will be specific strains of bacteria and/or Archaea present. For ammonia it will be Nitrosomas marina-like strains and for nitrite is will be the Nitrospira.
Identification of Bacteria Responsible for Ammonia Oxidation in Freshwater Aquaria
Paul C. Burrell, Carol M. Phalen, Timothy A. Hovanec
Applied and Environmental Microbiology Dec 2001, 67 (12) 5791-5800; DOI: 10.1128/AEM.67.12.5791-5800.2001
Abstract
Culture enrichments and culture-independent molecular methods were employed to identify and confirm the presence of novel ammonia-oxidizing bacteria (AOB) in nitrifying freshwater aquaria. Reactors were seeded with biomass from freshwater nitrifying systems and enriched for AOB under various conditions of ammonia concentration...........
Enrichments containing the Nitrosomonas marina-like AOB strain were most efficient at accelerating ammonia oxidation in newly established aquaria. Furthermore, if the Nitrosomonas marina-like AOB strain was present in the original enrichment, even one with other AOB, only the Nitrosomonas marina-like AOB strain was present in aquaria after nitrification was established.

About 4 years later it was discovered (in a large salt water tank in a public aquarium) that another micro-organism from another domain the and the was able to convert ammonia to nitrite. It has since been determined that these strains of Archaea dominate in the oceans and may be found both in soil and fresh water. You can read that paper here:
Isolation of an autotrophic ammonia-oxidizing marine archaeon
Archaea constitute a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria, but this classification is obsolete.

More recently it was discovered that Nitrospira can process ammonia to nitrate on its own. You can read the paper about this here:

Next, it is not the nitrite oxidizing Nitrospira which are patented, it is the probes which are required to detect them. And yes , I have read the patent filing as well as this paper. You can read the entire Patent filing here:
Method for detecting bacterial nitrite oxidizer
Nitrospira-Like Bacteria Associated with Nitrite Oxidation in Freshwater Aquaria
Timothy A. Hovanec, Lance T. Taylor, Andrew Blakis, Edward F. Delong
Applied and Environmental Microbiology Jan 1998, 64 (1) 258-264; DOI: 10.1128/AEM.64.1.258-264.1998
ABSTRACT
Oxidation of nitrite to nitrate in aquaria is typically attributed to bacteria belonging to the genus Nitrobacter which are members of the α subdivision of the class Proteobacteria. In order to identify bacteria responsible for nitrite oxidation in aquaria, clone libraries of rRNA genes were developed from biofilms of several freshwater aquaria. Analysis of the rDNA libraries, along with results from denaturing gradient gel electrophoresis (DGGE) on frequently sampled biofilms, indicated the presence of putative nitrite-oxidizing bacteria closely related to other members of the genus Nitrospira.........
In total, the data suggest that Nitrobacter winogradskyi and close relatives were not the dominant nitrite-oxidizing bacteria in freshwater aquaria. Instead, nitrite oxidation in freshwater aquaria appeared to be mediated by bacteria closely related to Nitrospira moscoviensis and Nitrospira marina.

Between the two papers on the ammonia and nitrite oxidizers you will bit there are six names. Dr. Hovanec is on both studies and there are 2 and 3 other different scientists involved.
At the time Dr. Hovanec was working one these papers he was employed by Marineland as their Chief Science Officer, Aquaria Inc. and he ran the Marineland labs located in Moore park, CA. The info below is from March 2005.

Marneland was eventually acquired by
Spectrum Brands as was Tetra. The patents were shared by Dr. Hovanec, and Marineland and their rights were what allowed Spectrum to have Tetra create Safe Start.
So, I will conclude by saying even though Dr. Hovanec and Spectrum Brands share the patens on the proves for Nitrospira, the three other researchers (Lance T. Taylor, Andrew Blakis, Edward F. Delong) on te Nitrite paper have no financial interest or ownership of the patent involved. In order to put Nitrospia into a bacterial starter product sold in the USA which contains Nitrospira as identified in the above paper, one must have probes to detect them. I also checked the bios for all three of co-author names, some are more well known researcher than Dr. Hovanec.
I have no financial interest in any of the above products and no connection to any of the names or organizations mentioned. What I know is that I have used the Dr. Tim;s One and Only product for over a decade and I can tell it works. But them I have only cycled tanks/filters with it into which I then added fish which cost as much as $5,000 into the tank almost immediately.
One more thing, Seachme knows all of the above, it is no secret, What they did decide to do is bury this older piece on their site:
Basics of Biofiltration
At the time Dr. Hocanec et. al. had not done the research above and Seachem, like everybody else, got the strains wrong. It wasn't until Dr. Hovanec's pH.D. thesis that it was shown these previous assumptions were wrong:
Comparative analysis of nitrifying bacteria associated with freshwater and marine aquaria.
T A Hovanec, E F DeLong
Applied and Environmental Microbiology Aug 1996, 62 (8) 2888-2896; DOI:
In the above paper it was discovered that the strains assumed to be in FW aquariums were not there.
